Manipulation of the quantum state by the Majorana transition in spinor Bose-Einstein condensates

Abstract

Manipulation of the quantum state by the Majorana transition in a spinor Bose-Einstein condensed system has been realized by altering the rotation frequency of the magnetic field direction. This kind of manipulation method has no limitation on the transition speed in principle, and the system is well closed. When this method is used on a pulsed atom laser, a multicomponent spinor atom laser is generated. We demonstrate that the experimental results agree with the theoretical prediction.
